Montmorency-Oscoda-Alpena Landfill: 989-785-6500
The Montmorency-Oscoda-Alpena Landfill (Landfill) located at 6751 Landfill Road, consists of 86.06 acres and is a licensed municipal Type II landfill. The landfill is owned and operated by the Montmorency-Oscoda-Alpena Solid Waste Management Authority (Authority). It has operated since 1977 and is surrounded by State of Michigan forest land. The Landfill primarily services a three-county area and has received domestic, commercial, and industrial solid wastes. The Landfill was originally operated as an unlined site and later converted to a double liner system. Due to on-site conditions, rainwater infiltrated into the unlined cells, which resulted in groundwater contamination. The Authority initiated a Remedial Action Plan addressing the groundwater contamination on January11, 2000, that was approved by EGLE.
Due to the groundwater conditions at the Landfill, and the likelihood that PFASs may also be present, EGLE requested the Authority conduct PFAS sampling. The Authority sampled select monitoring wells at the Landfill during the fall of 2019.
The Landfill is located in the center of large ridge (moraine). The groundwater flow leaving the Landfill is in two directions due to the ridge. The groundwater flows to the northwest direction in the perched aquifer on the west side, and in a northeast direction in the regional aquifer on the east side of the Landfill. Both aquifers discharge to the Thunder Bay River Watershed. Groundwater depths to the aquifers vary from 60 to over 100 feet. Groundwater contamination has been detected in both the perched and regional aquifers however, only the regional aquifer has detections of PFAS above Part 201 criteria. The nearest residential wells are over a 1 ½ mile away to the northeast. The Thunder Bay River is located 2 ½ miles down gradient of the Landfill in a northeast direction.

EGLE is working with the local health department to determine if there are any residential wells that need sampling. Future sampling will be based on findings of Remedial Investigation.
EGLE anticipates the sample results from the new monitoring well M-203 to be available by late summer.
